Die Erfindung bezieht sich auf eine Ringspinnmaschine mit auf- und abwärts bewegtem Streckwerk.The invention relates to a ring spinning machine with upward and downward movement Drafting system.

Um nun auf einer solchen Ringspinnmaschine feine Garne von hoher Garnnummer und lose gedrehte Schußgarne herzustellen, wird nach der vorliegenden Erfindung das Strecken und Drehen des Fasergutes derartig getrennt vorgenommen, daß der Faden inIn order to use such a ring spinning machine for fine yarns of high count and making loosely twisted weft yarns, according to the present invention, that Stretching and rotating the fiber material made so separately that the thread in

ίο einem Streckwerk zuerst gestreckt und nach Herauskommen aus dem Streckwerk der Drehung unterworfen wird, worauf der so gestreckte und gedrehte Faden auf der Ringspindel aufgewickelt wird.ίο a drafting system first stretched and after Coming out of the drafting system is subjected to rotation, whereupon the thus stretched and twisted thread on the ring spindle is wound up.

Nach der vorliegenden Erfindung erhält ein an und für sich bekanntes Streckwerk in der Ringspinnmaschine eine Auf- und Abwärtsbewegung, und bei der Aufwärtsbewegung wird das Strecken und Spinnen und bei der Abwärtsbewegung das Aufwickeln des gesponnenen Fadens vorgenommen. Zu diesem Zweck drehen sich die Streckwalzen während des Streckens und Spinnens, also beim Aufwärtsgang des Streckwerkes so oft, daß sie ein Stück Faden entsprechend der Länge des zurückgelegten Weges liefern. Beim Abwärtsgehen des Streckwerkes, d. h. beim Aufwinden des Fadens, wird von den Streckwalzen nur ein je nach der Güte des Spinngutes zu bemessendes kleines Stück Faden geliefert, wie dieses auch beim Selfaktor unter der sogen. Nachlieferung ganz allgemein bekannt ist.According to the present invention, a drafting system known per se is given in the ring spinning machine an upward and downward movement, and in the upward movement the stretching and spinning and the downward movement the winding of the made of spun thread. For this purpose, the drawing rollers rotate during drawing and spinning, that is so often during the upward movement of the drafting system that a piece of thread corresponding to the Provide the length of the distance covered. When going down the drafting system, i. H. When the thread is being wound up, the drawing rollers only produce one depending on the quality of the A small piece of thread to be measured is supplied, like this one with the self-actuator under the so-called Subsequent delivery is generally known.

Um hierbei während des Spinnens eine gleichbleibende und gleichmäßige Fadenspannung im Faden zu erzielen, wird die Ringschiene während des Streckens und Drehens derartig angehalten, daß der Ringläufer in der Ebene des größten Durchmessers des Wickelkörpers umläuft und hierdurch für jeden Streck- und Drehvorgang eine gleichmäßige Fadenspannung erzielt, wird. Um auch während der Ansatzbildung des Spulenkörpers den Faden ebenfalls auf der Spindel und den größten Durchmesser der Spule zu halten und eine gleichmäßige Fadenspannung zu sichern, ist auf der Ringspindel eine verschiebbare und mit zwei Ansätzen versehene Hülse, deren Durchmesser dem größten Spulendurchmesser gleich ist, derartig angebracht, daß die Ringschiene während ihrer Ruhestellung in eine derartige Lage kommt, daß der Faden sich um diese Hülse oder den Mitnehmer legt und hierdurch auf dem größten Spiilendurchmesser und mit derselben Fadenspannung gehalten wird. Kommt die Ringschiene alsdann wieder in Bewegung, so gleitet der Faden \^ron der Hülse ab und wird in bekannter Weise auf der Spindel aufgewickelt. In order to achieve a constant and even thread tension in the thread during spinning, the ring bar is stopped during stretching and turning in such a way that the ring traveler revolves in the plane of the largest diameter of the bobbin and thereby achieves a uniform thread tension for every stretching and turning process , will. In order to keep the thread on the spindle and the largest diameter of the bobbin even during the formation of the bobbin, and to ensure an even thread tension, there is a sleeve on the ring spindle with two lugs, the diameter of which is the same as the largest bobbin diameter attached that the ring rail comes during its rest position in such a position that the thread wraps around this sleeve or the driver and is thereby held on the largest spool diameter and with the same thread tension. Comes the ring rail then moving again, so \ ^r slides on the yarn from the sleeve and is wound in known manner on the spindle.

Auf beiliegender Zeichnung ist der Gegenstand der vorliegenden Erfindung in einem Ausführungsbeispiel dargestellt, und zwar in Fig. ι in einer Seitenansicht, während Fig. 2 eine Einzelheit im vergrößerten Maßstäbe veranschaulicht.In the accompanying drawing, the subject matter of the present invention is in one Embodiment shown, namely in Fig. Ι in a side view, while FIG illustrates a detail on an enlarged scale.

Claims

The drafting system α is attached to a carrier b arranged along the machine and the latter to the guide bush d guided on a rod, which is moved up and down by chain e and chain rollers // 1 by moving the chain roller f1 forwards or backwards. Chain roller / 1 sits on a shaft g, which is arranged along the machine and driven in any way. During the upward movement of the drafting system α, the material to be spun runs off roving bobbins i set in rotation by means of stripping rollers h, passes the thread guides k, runs over the rotating conveyor rollers / Z1 and arrives at the drafting system a. After the roving is warped, i.e. H. has been refined, it receives rotation when it emerges from the front cylinder of the drafting system. The finished thread goes through the thread guide m and is then wound onto the spindle by the rotation of the spindle η in conjunction with ring traveler 0 and the ring rail%, λνο-when the spindle η is driven from the drum ρ by spindle cord. The ring rail only moves up and down during the winding up to form the kötz; this movement is achieved in a known manner, namely by lifting rods q, which are moved by a winch device. In order to achieve an even thread tension during spinning, the movement and the position of the spindle rail is regulated in such a way that the ring traveler guiding the thread ο always rotates in the plane of the largest diameter of the bobbin during stretching and turning, so that the thread tension When the thread is turned, it always remains the same, at which point the ring bar is held in its lowest position during the entire stretching and turning process. Since a uniform thread tension should also be achieved during the formation of the bobbin, a sleeve n> is attached to the spindle η (see FIG. 2) in such a way that it rotates with the spindle and can be shifted slightly on the same. At the upper edge, the sleeve yv is provided with two small lugs or lugs wl to make it easier to take the thread with you. In order to achieve the laying of the thread on the sleeve and the release of the thread from the sleeve in the lowest position of the ring rail, the sleeve w is somewhat vertically displaceable on the spindle η, in such a way that in the highest position of the sleeve w the Thread comes to rest on the same. For the purpose of guiding the sleeve in the vertical direction, a lever s rotatable about the bolt r is moved from the lower part q1 of the lifting rod q (Fig. 1) during the formation of the Kötzers and by means of a pull rod t the lever ν rotatable about the bolt u is moved. The end of the lever ν is forked, engages around the sleeve or the rotor driver w and. moves the same upwards in the formation of the Kötzer in accordance with the ring rail \ such that the thread wraps itself around the sleeve iv when the ring rail \ goes down and is thus held on the largest bobbin diameter, whereby the lugs wl ensure easy removal of the thread . When the ring rail moves upwards, the thread slides off the tube w and is wound onto the spindle. When the build-up has ended, the runner driver w is put out of action. Ρλ'τεντ claims:

1. Ring spinning machine with upward and downward moving drafting system, thereby characterized in that when the drafting system is up, both the stretching of the Roving made by the drafting system itself as well as the one that has already been drawn The thread is rotated and the spun thread is wound up during the downward movement, with the aim of achieving constant thread tension during spinning. the location of the largest coil diameter stands still.

2. Ring spinning machine according to claim 1, characterized in that in order to achieve the constant thread tension during the formation of the bobbin on the spindle Sleeve rotating with the spindle of the same diameter as the largest Spool diameter is mounted displaceably so that at the lowest position of the ring rail, the thread is around the Sleeve lays.
